Three issues. 1. Very soft, blurry images in low light at long distances. Went through two 70-200mm VRII's before I figured out it was the body, not the lens. 2. When using a 2 or 3 exposure burst the exposures are all different..(not using flash) and 3. Metering is off by a 2-3 stops.

I know they are abnormal. I've never seen them as complaints here for this body. I use this camera in my business a great deal in long distance/ low light situations. This is why I bought this body and lens. I don't use a tripod and prefer to not use a monopod either. I have to hand hold. I've tested the lens in identical situations with several different bodies and it is reasonably sharp on other bodies. I'm talking about standing in the same place at the same time rotating the lens through several bodies. D600 - blurry. Shutter speeds up to 400. Some times in the situation it back focuses.. even at medium ranges it back focuses. The problem is, that it isn't consistent. I'm very frustrated with it right now.

In good light, it works much better at long distances and is spectacular close up.

Just an update on this. They finished the repair and shipped it today. They said they replaced the "Image PCB Board." or something like that.. otherwise they just adjusted stuff. Any idea what that part is and what it does?
